Optic Nerve Hemangioblastoma

Optic Nerve Hemangioblastoma: A Case Report

Hemangioblastomas are World Health Organization (WHO) grade I tumors of uncertain histologic origin. These central nervous system tumors are most often found in the posterior fossa, brainstem, and spinal cord. There are fewer than 20 reported cases of optic nerve hemangioblastomas in the literature. We present a patient with visual decline found to have a mass arising from within the posterior ...

Hemangioblastoma of the optic nerve: radiographic and pathologic features.

A 15-year-old black boy had decreasing visual acui ty and progressive proptosis in the lett eye for 6 months. Ph ysical examination showed a mildly proptotic left eye with light percept ion only, a Marcus Gunn pupil , and a pale disc on fundoscopy. The rig ht eye was entirely normal.

[Hemangioblastoma of the spinal nerve root].

A case of extramedullary spinal root hemangioblastoma is described. A 44-year-old male presented with gait disturbance. Magnetic resonance (MR) imaging revealed a round enhanced mass at the level of T8. Spinal angiography showed a vascular tumor fed by the posterior spinal artery via the left T9 intercostal artery. A laminectomy of T8-T9 was performed, and a reddish brown-colored soft tumor ori...

Effect of scuba-diving on optic nerve and sheath diameters

  Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
